Methane Adsorption on Cu-BTC110 Metal-Organic Framework

Effect of CuBTC Composition, Structure, and Morphology on the Catalytic and Antimicrobial Properties

“…The behavior of I 111 , % on the model and experimental XRD patterns of [Cu 3 (BTC) 2 ], [Cu 3 (BTC) 2 (H 2 O w ) 2.5 ], [Cu 3 (BTC) 2 (H 2 O w ) 3 ], [Cu 3 (BTC) 2 (H 2 O w ) 3.42(12) ] × 3.54H 2 O, and [Cu 3 (BTC) 2 (H 2 O w ) 3 ] × 6H 2 O makes it possible to estimate or compare the content of extra framework water in different samples; on the XRD patterns of [Cu 3 (BTC) 2 (H 2 O w ) 3 ] × n H 2 O (3.54 ≤ n ≲ 6; data for n in the range of 3.54–6 are unknown) with n > ∼3.54 , a 111 reflection should be present and the intensity ratio should be changed ( I 200 , % < I 222 , % > I 220 , %), which becomes the same as that for [Cu 3 (BTC) 2 (H 2 O w ) 3 (DEF) 3 ] × n DEF.…”

“…Thus, the [Cu 3 (BTC) 2 ] model diffraction patterns contain a 111 peak, which is absent for It is interesting to note that the indicator peaks ratio (I 200 , % < I 222 , % > I 220 , %, I 333,511 , % < I 404 , %) on the [Cu 3 (BTC) 2 (H 2 O w ) 2.5 ] sample diffraction pattern 33 does not exclude the real composition of [Cu 3 (BTC) 2 (H 2 O w ) 2.5 ] × nDMF with N,N′-dimethylformamide (DMF) solvent molecules in the framework voids, which is consistent with the synthesis conditions. On the other hand, on the XRD pattern of the commercial Basolite C300 sample, 34 a similar intensity ratio allows writing its composition as…”
